Апстракт:
The parallel plate method serves as one of the basic approaches in dielectric spectroscopy measurements. This method is based on placing a thin layer of dielectric sample between two electrodes, forming a capacitor-like structure. A key requirement for accurate measurements in this case is to ensure good contact between the electrodes and the sample over the entire surface. To ensure this, one of the most widely applied solutions is the use of conductive paste, which improves both the contact and the repeatability of the measurements. In this study, measurements were carried out on bentonite samples, a material known for its great swelling capacity and high sensitivity to moisture. To overcome the limitations associated with conductive paste due to these properties of bentonites, graphite layers were applied to the samples. The influence of the graphite coating, aimed at improving the electrode-sample contact, on the measurement results was systematically investigated. For the purposes of this study, admittance (Y) was selected as the quantity to be analyzed, with a focus on measuring the frequency-dependent behavior of conductance (G) and susceptance (B).
